84174-04-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 84174-04-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,1,7 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 84174-04:
(7*8)+(6*4)+(5*1)+(4*7)+(3*4)+(2*0)+(1*4)=129
129 % 10 = 9
So 84174-04-9 is a valid CAS Registry Number.

Transient and Matrix Ultraviolet Absorption Spectra of Dimethylgermylene (Dimethylgermanediyl)

Tomoda, Shuji,Shimoda, Masakatsu,Takeuchi, Yoshito,Kajii, Yoshizumi,Obi, Kinichi,et al.

, p. 910 - 912 (2007/10/02)

Dimethylgermylene (1), generated from a new precursor dimethylbis(phenylseleno)germane (2), has been observed as a transient species by time-resolved laser flash photolysis at room temperature.

Chemistry of Heavy Carbene Analogues R2M (M = Si, Ge, Sn). 8. Germylenes: Singlets or Triplets? Cheletropic Cycloadditions of Me2Ge and GeI2 to Conjugated Dienes

Schriewer, Michael,Neumann, Wilhelm P.

, p. 897 - 901 (2007/10/02)

Thermally generated germylenes Me2Ge undergo in solution under mild conditions (70-150 deg C) concerted 1,4-additions of the linear cheletropic type to certain 1,3-dienes.Thus, the highly reactive meso diallene 10a gives, in a about 1:1 ratio, only the two isomeric 1-germacyclopentenes 11a and 11b expected from front- and back-side attack of Me2Ge, whereas the D,L-diallene 10b produces only the third isomer, 11c, in accordance with this mechanism.The yields are about 70percent; the isomer purity is >/= 98percent.Likewise, two other E,E-1,4-disubstituted 1,3-butadienes give only the corresponding cis-2,5-disubstituted 1-germacyclopentenes 7a or 9a in 80percent or 30percent yields with an isomer purity of >/= 98percent (limit of the NMR analysis).Similarly, with GeI2 and 10a, only 14a and 14b are found, and 14c with 10b, as expected for a cheletropic reaction.Methylation of 14a-c yields the corresponding compounds 11a-c.Other mechanisms for these 1,4-additions are discussed but are highly unlikely: thermal germylenes Me2Ge and Ge2I behave as singlets.
